Creates lists of non-hierarchical taxonomies (such as <code>post tags</code>) as an alternative to term (tag) clouds. Multiple widgets can be used, each with its own set of options.
Numerous formatting options are provided, including maximum numbers of terms, term order, truncating of term names, and more. List styles are fully customizable, with built-in support for bulleted lists and numbered lists.
Using the <code>taxonomy_list_widget</code> function, users can generate lists for use outside of the included widget.
Only use version 1.2 or higher with WordPress 4.2 and later releases. WordPress 4.2 changed how taxonomy information is stored in the database, which directly impacts this plugin’s include/exclude term functionality.
This plugin was formerly known as the <code>Tag List Widget</code>. It was completely rewritten for version 1.0.

Tag Selector adds an additional meta box to your page/post edit pages that allows you to select tags for your post/page much the same way you select categories. This is especially nice if you have more tags than you keep track of and don’t have time to wait for predictive text results.

Tag Selector

This plugin is exceptionally useful for bloggers. That said, the reason it received only 4 stars out of 5 is because the meta box shows up at woocommerce products as well, which of course the post tags are irrelevant. I'm sure the same would happen for all other custom post types.
The meta box has to be displayed only on blog posts - other than that... this plugin is perfect, thank you !!!



Very helpful but not "idiot-proof"

I wanted to select tags/no-hierarchy taxonomies just like i select categories and it solves this problem. But it forces to select only one taxonomy. If this feature was optional Would be great.

Almost what i wanted

Tag Selector allows you to select tags for your post/page much the same way you select categories.
